Answer:

64 cubic metres

Step-by-step explanation:

The triangular pyramid volume formula resembles the volume formula for any other pyramid or cone:

V = A * H / 3

where:

A is the area of the pyramid's base

H is the height from the base to the point

In other words: the volume of a triangular pyramid is one-third of the product of the base area and the pyramid's height.

8 x 6 / 2 to find area of base = 24

x 8 = 192

192 / 3 = 64

Hope this makes sense. If you would like, I can l1nk to a very useful website, or I can explain it further.

Answer:

  • large: 55 lb
  • small: 30 lb

Step-by-step explanation:

Let x and y represent the weights of the large and small boxes, respectively. The problem statement gives rise to the system of equations ...

  x + y = 85 . . . . . combined weight of a large and small box

  70x +50y = 5350 . . . . combined weight of 70 large and 50 small boxes

We can subtract 50 times the first equation from the second to find the weight of a large box.

  (70x +50y) -50(x +y) = (5350) -50(85)

  20x = 1100 . . . . simplify

  x = 55 . . . . . . . divide by 20

Using this in the first equation, we can find the weight of a small box.

  55 +y = 85

  y = 30 . . . . . . . subtract 55

A large box weighs 55 pounds; a small box weighs 30 pounds.

Answer:

135

Step-by-step explanation:

The given expression is

\frac{2 {x}^{2} }{x} +x(100 - 15x)

From the question, x=5

So,by substitution,we obtain

=\frac{2({5}^{2})}{5} +5(100 - 15(5))

=\frac{2(25)}{5} +5(100 - 75))

=2(5)+5(25)

= 10+125

= 135

Hence the answer is 135
